Without much hype and big promises AMD launched a graphics accelerator that not only took its place in the company’s product lineup, but also called in questions about the existence of three other graphics cards in the family. Our today’s review will unveil which graphics cards these are and why it happened in the first place.

Total War: Shogun 2

What makes this game different from the previous ones is that the Radeon HD 6930 and HD 6870 feel a lack of graphics memory. They only have 1 gigabyte of it. Besides having a very low bottom speed, these cards were unable to run the test with antialiasing turned on.

Crysis 2

The bottom speed of the Radeon HD 6930 and HD 6870 is low in Crysis 2, too. The Radeon HD 6970, having more memory, beats them in this respect, especially with enabled antialiasing. Besides, this test is special because the Radeon HD 6870 beats the HD 6930 when both work at their default clock rates. This is thanks to the higher frequency of the Barts XT processor.

DiRT 3

DiRT 3 doesn’t produce anything unexpected. Its results agree with those of most other tests.

Hard Reset Demo

The Radeon HD 6930 and Radeon HD 6870, each with 1 gigabyte of onboard memory, have problems with the bottom frame rate in Hard Reset Demo. They can only deliver 10-12 fps whereas the Radeon HD 6970 2GB never slows down below 35 fps. The standings are normal in the MSAA-less mode.

Batman: Arkham City

This game ranks the graphics cards as accurately as 3DMark Vantage.

Battlefield 3

The standings are the same as in the previous tests. So, let’s move on to summary diagrams.
